To use these pins, it will be necessary to drill a hole completely through the rudder cheek and blade assembly. Doing so will expose the foam core of the rudder to water intrusion.
To avoid saturating the foam core:1) Drill a 3/8" hole entirely through the cheek/rudder blade assembly.
2) Remove the rudder blade from the cheeks.
3) Drill the hole through the rudder blade again, this time a larger diameter, perhaps 1/2" or 5/8" in diameter.
4) Fill the hole in the blade with a mixture of West epoxy and high density filler found in the Small Repair Kit (found below under "May we also suggest").
5) After the epoxy is fully cured (a day or two later), reinstall the rudder blade into the rudder cheeks.
6) Using your original 3/8" hole in the cheeks as a guide, drill through the center of the epoxy plug you created in the last step.Following these steps will create a waterproof epoxy sleeve in the fiberglass/foam rudder blade and prevent water intrusion into the foam core.

'splained.

perfect, thx!

anyone done this or similar solution to premature rudder kick-up syndrome? Looks simple enough and solves the problem...

Yeah man, it works just fine. We had no complaints with it.

Done, eze/inexpensive fix to an annoying/poor design...(and musta been a known issue back in '84, the aluminum cheeks were already factory drilled 3/8", the rudder blade was not...)
